Anchor version Benefits
HDA-P HDA-PR HDA-PF Anchor for pre-setting HDA-T HDA-TR HDA-TF Anchor for through-fasting
- suitable for non-cracked and cracked concrete C 20/25 to C 50/60
- mechanical interlock (undercut)
- low expansion force (thus small edge distance / spacing)
- automatic undercutting (without special undercutting tool)
- high loading capacity, performance of a headed stud
- complete system (anchor, stop drill bit, setting tool, drill hammer)
- setting mark on anchor for control (easy and safe)
- completely removable
- test reports: fire resistance, fatigue, shock, seismic

For spacing (edge distance) smaller than critical spacing (critical edge distance) the design loads have to be reduced. Critical spacing and critical edge distance for splitting failure apply only for non-cracked concrete. For cracked concrete only the critical spacing and critical edge distance for concrete cone failure are decisive.
Simplified design method
Simplified version of the design method according ETAG 001, Annex C. Design resistance according data given in ETA-99/0009, issue 2008-03-23.
� Influence of concrete strength � Influence of edge distance � Influence of spacing � Valid for a group of two anchors. (The method may also be applied for anchor groups
with more than two anchors or more than one edge. The influencing factors must then be considered for each edge distance and spacing. The calculated design loads are then on the save side: They will be lower than the exact values according ETAG 001, Annex C. To avoid this, it is recommended to use the anchor design software PROFIS anchor)
The design method is based on the following simplification: � No different loads are acting on individual anchors (no eccentricity)
The values are valid for one anchor. For more complex fastening applications please use the anchor design software PROFIS Anchor.

For the recommended loads an overall partial safety factor for action γ = 1,4 is considered. The partial safety factors for action depend on the type of loading and shall be taken from national regulations. According ETAG 001, annex C, the partial safety factor is γG = 1,35 for permanent actions and γQ = 1,5 for variable actions.
